My invention relates to that class of toilet tionof a slitting andperforating-machine to paper roll inr which the central core of thewhich my improvements are applied. roll is formed integral with thecontinuous The paper'roll shownin Fig.1 comprises web wound about thecore, whereby the core a corrugated core/2 of multi-ply construction androll is formed from a continuous length and produced by winding a pastedweb upon of paper and at a single operation. itself While supportedupon'a corrugated In carrying out my invention, I wind the mandrel andpressing the pasted web= into advancing end of a paper web between rollscorrugated relation by a squeeze roll 4 shown having corrugatedperipheries and, at the n Fig. 2. The corrugated multiple ply core webso that the same is wound upon a corstruction which, while havingreasonable plirugated mandrel and. pressed into a multiability, retainsits shape and thus provides ply corrugated core upon which the web may acore member within the body of the combe continuously wound but withoutthe appleted roll. Whenthe corrugated core is replication of glue, withthe result that a finleased from pressure of the squeeze roll and ishedtoilet roll package may be produced the application of-glue, the furtherrotawith a corrugated core. tion ofthe mandrel will cause the fiat webIn the manufacture of paper of this char-. of paper to be wound,cylindrically about and acter, the wide web may be slit into a pluuponthe corrugated core and as a continuarality of narrower webs and thesenarrower tion thereof, as shown at 3-and as will be 7 webssimultaneously wound upon the same understood by reference to Fig. 1..The diammandrel in producing the-finished roll with eter and length ofthe roll may be varied to the corrugated core. suit the. requirementsofflthe manufacturer.

The glue applying'jroll 14' is preferably made of corrugated form so asto cooperate with the mandrel roll 13, and while thesaid glue applyingroll will not'only apply the glue but will also being formed upon themandrel, I prefer to employ an additional corrugatedroll 4 arrangedabove the mandrel 13 and having weight sufficient to insure the Icorrugation and press the paper into theglued recesses todensify themultiple-plyroreduring its formation. The corrugating orpress roll 4maybe journaled ina hinged frame 18 which will insure proper-presentationof the mandrel 13, or permit it to be turned upout of theway after thecore has been formed and during the winding of the cylindricalweb 3about'the core. it is customary to provide a pivoted mandrel frame 19 inwhich a plurality ofthe mandrels 13 may be journaled, so that saidmandrelsmay be successively brought into operative relation with theglue applying roll and press roll; The

mandrel may be driven inthe usual manner by a friction drive (not-shown)which will permit compensationforthe' different diameters of the rollbeing wound. The general character of a slitting and roll winding ma.-

When the multi-ply'core' has been completed by thecooperation of themandrel 13,

' glue applying roller- 14, and press roll 4, the

said glue applying roll and press roll'are moved out ofv cont'aetwiththe mandrel or core and thereafter the roll is completed by theuncorrugated portion of the web as at 3 in Fig. 1. When the properdiameter of roll is formed the-mandrel carrying frame 19 is shifted tobring anew mandrel into operative relation with the web and, at the;sametime,

to move the completed roll to the rear as 'shown in Fig. 4: 9

amount of elasticity or which may be resorted toas the multi-ply corethanwould'be required because the celllike formation between the coreand the cylindrical portion of the roll gives a bracing effect with alesser quantity of paper web than would be required in a cylindricalcore of the same strength. Furthermore,.the corrugated form of thecoregives a certain yieldingness at its points of internal contact thanwhen threadedlupon a cylindrical support and, moreover,

may be rotatable upon saidsupport but normally positioned thereonwithout objectionable looseness. It will be understood that thiselasticity of the core may be utilized to impart a reasonable dragthereon when withdrawing the web of paper therefrom, so that th'ere'willbe no unnecessary tendency to spin and obj ectienably unwinding theroll.
